Sorry, I have not explained well.
The problem was related to the value of C map. That is, I take the example
above. If the value of C map is equal to 1, I get a result - A =12 B=3323
C=1 =12332301 (8 digit number) and instead could be useful 1233231 (number
7-digit).
However I checked and I need
Excellent Alex:). The maps are as follows:
A - value 0, 1, 2, ... 19
B - value 0, 1001, 1002, 1003 3351
C - value from 0, 1, 2, 3, 4 .. 15
So, I did as you suggested:
r.mapcalc output = (( A *100)+( B *100)+ C )
right?
And if I had decimal numbers or strings instead of numbers?

Hi Achim.
Returning to the problem of the three maps in some cases remain the problem
(for example for the map C), because some numbers are 2 digits and another
with 1 digit.
For example, with values A = 12 B = 3323 C = 1 instead of 1233231 I have
